Kipping pull-ups have lower muscle activation in the upper body but greater activation in the lower body and core; it is possible to perform them faster and complete more repetitions before encountering upper-body fatigue. [14] Kipping pull-ups are considered high risk for injury and are a major cause of shoulder injury in CrossFit athletes. [15]
The chest fly is performed while lying face up on a bench or standing up, with arms outspread holding weights, by bringing the arms together above the chest. This is a compound exercise for the pectorals. Other muscles worked include deltoids, triceps, and forearms. Equipment: dumbbells, cable machine or "pec deck" machine.
Olson shares that “negative pull-ups” are also a great starting point. “Use a chair or bench. Hang from a pull-up bar in the flexed (ending/up) position,” she explains of the exercise.
Chin-ups work the biceps, forearms, chest, and several upper back muscles, particularly the latissimus dorsi, trapezius, and rhomboid muscles. Pull-ups, when one's grip is wide with the palms facing away from the user, are also common. One attempts to pull himself up and touch his chest to the pull-up bar.
When the athlete has reached initial failure (i.e. fails to perform a further repetition), rather than ending the current set, the exercise can be continued by making the exercise easier (switching to another similar exercise e.g. pull-ups to chin-ups, switching to another (correct) form of the same exercise, switching to lower weight) or by recruiting help (from a spotting partner or by ...
Combined dip and pull-up machine with weights. Usually dips are done on a dip bar, with the exerciser's hands supporting their entire body weight. For added resistance, weights can be added by use of a dip belt, weighted vest, or by wearing a backpack with weights in it. A dumbbell may also be held between the knees or ankles.
One study showed that the inverted row activated the latissimus dorsi muscles, upper back, and hip extensor muscles more than the standing bent-over row and also resulted in less load on the lower spine area, which makes the exercises preferable for people with lower-back issues compared to other rowing exercises.
